Hi,

can you send us this file from the hypervisor:

/var/lib/one/datastores/0/<vmid>/deployment.0
and run this command:

    Hello!

    I set up a cluster of 3 nodes Opennebula and Ceph.
    Operating system Ubuntu 14.04.

    libvirt version:
    libvirt-bin - 1.2.2-0ubuntu13.1.2
    libvirt0 - 1.2.2-0ubuntu13.1.2

    qemu version:

    qemu-user - 2.0.0+dfsg-2ubuntu1.2
    qemu-utils - 2.0.0+dfsg-2ubuntu1.2

    Try to install Debian using debian iso.

    VM template:
    CPU="0.5"
    DISK=[
      IMAGE="debian 7",
      IMAGE_UNAME="jakal" ]
    DISK=[
      IMAGE="Debian",
      IMAGE_UNAME="jakal",
      READONLY="yes" ]
    FEATURES=[
      ACPI="yes" ]
    GRAPHICS=[
      LISTEN="0.0.0.0",
      TYPE="VNC" ]
    MEMORY="512"
    NIC=[
      NETWORK="LAN",
      NETWORK_UNAME="jakal" ]
    OS=[
      BOOT="cdrom" ]

    But when the virtual machine starts, I get the following message:
    "Booting from DVD/CD...
    Boot failed: Could not read from CDROM (code 0004)
    No bootable device."

    I tried looking for this problem on the internet and I have not
    found the cause of this error.

    Tell me, please, what can I do to resolve this situation?
    Thanks in advance for your assistance.

    Best regards,
    Aleksey Zolotukhin
